The helt iii, which is driven by the-motor ii, engages the pulleyi8 and the entire driving mechanism of b sleeve.

2' reams the device functions through gears 3'! and 38. Located withinand adjacent the ends of sleeve 83 is a pair of oilless bushings 39which serve to mount a shaft fill out of contact with the One end ofthis shait projects beyond the boss 29 and is fitted with a gear M. Theother end of the shaft dd projects into the cas- Inc I! and beyond thegear dd is splined as at 42. The boss is is formed with a further openlbing 43, located above the opening. or, whichconnects the interior of thecasing'll with the enterior. Within the opening 63 is a tube dd thatserves as a shaft to mount an ironing roll ed. at one end, the roll ieis supported on the tubelt by a plate 51, along a flange dd thereof.Centrally of the plate M is an opening in which is fitted a suitablebearing dd. The end of the roll it, adjacent the casing it, has aninterior member N that is formed with an annular collar 52 m throughwhich the tube projects. All outer flange 53 of the member bl is securedto the roll dd in'any suitable manner as by rivets. The

inriersurface of this flange is formed with n teeth 54. which areengaged by the teeth of gear it! located on the outer end of shaft it.

- Reference is now had to Fig. 6 of the drawings wherein the boss Si isprovided with an opening 5?. The boss 3! in cooperation with a bracket58 supports a tube 59, through which a rod iii projects. The tube 59 atone end projects into the boss ti terminating substantially flush withthe interior face of the wall 22 and at the other end within the bracket58. The rod ti projects s into the casing H and mounts a rocker arm 62which lies adjacent the wall 22 and terminates beneath the shaft dd, Theouter end of the shaft ti projects beyond the bracket tit and is fittedwith a presser arm $3. This arm (see Figures 3 and 6) includes a channelmember E56 4% having an interior block 65. A pin ht keys the block tothe shaft ti. The block is formed with -a finger d! that lies adjacentthe base wall of the channel and through which is a threaded openingtil. A recess Kit in the block 8b accomn modates one end of a leaispring Eli. A screw it projects through an opening in the base wall ofthe member st and is engaged with the threads of the opening dd, beingadjustable to move into pressure contact with the spring H and move thefree end thereof into pressure contact with a link it. The link "it ismounted on a pin it, the ends of which are supported on the side wallsof the channel member M. A threaded opening it in the link is is adaptedto receive M one end of the shaft H to which is amxed a handle 6r knobit. An ironing shoe W is provided with a recessed bracket Si in which aportion of the link 18 is positioned.- A pivot pin 82 connects thebracket M with the link. it. It will 3 be noted that the portion of thelinls it lying within the member 84 is formed with a flat face 83against which the spring H presses when the rod ll and shoe l9 assumethe position shown in. Fig. 3. Under normal operation of the machine,

$ shaft 6! is reciprocable and swings the ironing shoe 19 into or out ofironing position. However, in the event the mechanism within the casingceases to iunction or for any other reason it is necessary to withdrawthe ironing shoe 19 from 70 pressure contact with the roll 46, .the knobIt may be moved rearwardly of the device causing' the substantiallystraight line connection between ,arm 13 and shoe 19 to be broken andthe shoe is thus immediately released.

:16 Within the casing ll, between wall 22 thereof so secured to the wall22. Adjacent the shoulder 87 is an eccentric 95. This eccentric ispreferably integral with the member 84 and provides anouter surface onwhich is mounted an eccentrio strap M. The strap 92 includes an arm 93which is pivotally joined at one end to the rocker arm 82 through a pin94. In onedorm the rocker arm it? is provided with'a slot for receivingthe arm d8 of the eccentric strap, 92. Adjacent the eccentric M and alsoforming a part of the member M is a radially extending arm Qt. A lugsills provided on one face of the arm 96, being drilled to receive a pin9b which pivotally mounts one end of a dog 99. Another arm 800 projectsradially from the center of the member ti t in a direction opposite toarm st. A small 25 opening not is made in the end of this arm for thepurpose of securing one' end of a spring H12.

It will be noted that an annular shoulder its is provided at theopposite end of the member tit from theshoulder $1. This shoulder servesv to mount a plate Md. The plate W t is rotatable about the shoulder M3within limits hereinafter set forth. At opposite ends the plate isprovided with fingers I105 and its. Adjacent the sheer we the plate isfitted with a pin m which projects into a slot its in'the dog 99. Sinceone end of the dog 99 is pivotally mounted on the lug st of the arm 86and the other end thereof is limited in movement to the size of the slotE08 and also, the pin it! is attached to plate it, 40 it is apparentthat movement of the plate will cause the dog to rotate about its pivot98 in a direction to move a lug its on the dog radially toward or awayfrom the axis of rotation of the plate tilt, Adjacent the pin lt'l, theplate it so is formed with an opening lit which serves to secure theother end of spring E82. Adjacent the finger its is an opening iii whichsecures one end of a spring H2. The other end of the spring M2 is joinedto the end of the dog 99 adjacent the .pivot pin it. It will thus benoted that movement of the dog abo'utthe pivot 98 to move lug itsradially away from the rotational center of the structure changes therelative position of plate tilt and dog 99 and increases the tension onsprings its and M2.

v Projecting through a suitable supporting lug in the end wall 22 of thecasing is a rod H3. On the outer end of the rod is located a controllever Wt. The inner end 01 the rod lying within the interior of thecasing I1 is fitted with an arm its, the end lid of which takes the formof a finger trip. The arm 5 is normally held in the position shown inFig.. 9 of the drawings by a spring ill.

' 4 and 5 of the drawings wherein a mechanism for starting and stoppingtheroll 66 is shown. The gear 34, which rotates continuously when themachine is in use, is provided with teeth H9 'on that face of the hubopposite to the teeth I II.

and the member I is rotatable therewith. The

member I20 is formed with a series of laterally projecting teeth I 2|which, under certain circumstances of operation 'of the device, meshwith the teeth H9. The member is also formed with an annular groove I22.A bracket I23 is secured to a bottom flange of the casing in anysuitable manner as by screws I24. This bracket is provided withupstanding end lugs I25 having openings to receive a shaft I26. Thecentral portion of the shaft I26 is squared and a pair of spaced apartarms I21 are mounted thereon. Adjacent.

their upper ends, the arms are provided with pins I28 which fit theannular recess I22 of the member I20. The arms I21 terminate in fingersI29. The cover plate 23 of the casing I1. is formed with lugs I3Ithrough openings in which a rod I32 projects. One end of the rod extendsbeyond an edge of the cover plate and is fitted with a control leverI33. Between the lugs It" a pair of slots I34 are made in the rod I32which are in vertical alignment with and adapted to receive the fingersI29 of arms I21.

Secured to the squared portion of the shaft I 26 is an arm I36 whichterminates in a finger portion I31 that rests on the rocker arm 62. Aspring I38 is secured at one end 'to the rocker arm and at the other maybe fastened to one of the screws I24. The purpose of this spring is tocause the finger I31 of the arm I36 to at all times contact the rockerarm 62 and also urge fingers I29 of arms I21 into contact with the fiatsurfaces of the recesses I34 and the rod I32.

For a clearer understanding of the invention the description of theoperation thereof commences with the ironing shoe 19 in open positionand the elements of the drive and clutch mechanism in the position shownin Figure '7 of the drawings. It will be understood that during use ofthe ironing machine the motor I4 runs continuously and, through belt I6,rotates pulley 28, shaft 38, and gear 34. Until such time as the shoe 19is to be moved into operative position and the roll 46 rotated, gear 34rotates freely about sleeve 33. The lever H4 serves to control theironing shoe 19 and allow it to move into pressure contact with the roll46. When this lever is depressed, arm H5 is swung upwardly causingthe'portion H6 thereof to disengage the finger I05 of the plate I04.Attention is directed to the fact that so long as the portion H6 engagesfinger I05, the relative position of the dog 99 and plate I04 remains asshown in the drawings. This is due to the fact that the spring 68 whichencircles the member 84 has a frictional contact therewith and tends torotate with any attempted rotation of this member. The end of thisspring, however, is anchored against such rotation and thus member 84can only rotate against a frictional wrap around tension of the springin this direction. Inasmuch as the spring 88 is stronger than either orboth springs I02 and causes pin I01 to swing the slotted end of the doginwardly moving the lug I09 into mesh with the teeth H8. This positionof the elements of this portion of the mechanism is clearly shown inFigure 8 of the drawings. Gear 34 is thus caused to rotate member 84,plate I04, and dog 99. The eccentric 9| on the member 84, on which theec centric strap 92 is mounted, is thereby caused to rotate. At thecommencement of this operation it will be understood that the eccentricstrap 92 was in raised position and through its connection with therocker arm 62 maintained the ironing shoe 19 in inoperative position.Rotation of the eccentric 9I one hundred eighty degrees,'moves theeccentric'strap 92 downwardly through the position shown in Figure 8 tosubstantially that of Figure 9. Finger I 06 now comes into position andis engaged by the portion H6 of the arm I I5 and further rotation of themember 84, plate- I04 and dog 99 is thus prevented. Again due to thefrictional engagement of the spring 88 with the member 84, the dog 99and plate I04 are caused to have relative movement and assume theposition shown in FigurelO. At this point the ironing shoe is inoperative position.

During the one hundred and eighty degree rotation of the abovemechanism, the eccentric strap 92 has moved rocker arm 62 downwardly andarm I36 has rotated about shaft I26 by reason of the tension of springI38. Since shaft I26 has been caused to rotate, arms I21 have movedlaterally causing the member I20 to move along shaft "40 and the teethI2I .thereof to inter engage the teeth H9 located on the hub of the gear34. Rotation of shaft 40 causes the roll 46 to rotate through engagementwith teeth 54 of the member 5|.

When it is desired to release the ironing shoe 19 and stop rotation ofthe roll 46, the lever H4. is again depressed to raise the arm H5 andrelease finger portion H6. The dog 99 again engages the teeth II8 ongear 34 and this portion of the structure rotates until finger I05 againstrikes the portion H6 of arm I I5 and the elements are in the positionshown in Figure 7, and

the ironing shoe is in inoperative position. During the process ofopening the ironing shoe, rocker arm 62 has swung upwardly causing armI36 to move upwardly and moving arms I21 later-' ally to disengage theteeth I2I of the member I20 from the teeth H9 of the gear 34.Disengaging these sets of teeth stops rotation of the shaft 40 and roll46.

It is sometimes found desirable to press an article in a device of thisclass by simply moving the ironing shoe into contact with the roll whennot in motion and since rotation of the roll of this device is madeautomatic with the operation of the ironing shoe, an auxiliary structureis provided in the form of the lever I33. When this lever is rotatedfroma horizontal to a vertical position, the shaft I32 is rotated. The edgesof the slots I34 contact the fingers I29 of arms I21 moving said armslaterally to disengage the teeth I2I of member I20 from the teeth H9 ofthe gear 34. When it is.

desired that the machine again operate in the usual manner the lever I33is moved into the position shown in Figures 1 and 2 of the drawings androtation of the rpll again becomes automatic.

Although applicant has shown and described only one modification of hisinvention in connection with an ironing ,machine, it will be apparent tothose skilled in the art that variations or adaptations of the structureherein shown and described may be made without departingfrom the spiritand scope of the invention as defined in the hereunto annexed claims.
